Abstract

An image forming apparatus in which toner left on a seal sheet after transfer is deposited under a high-temperature, high-humidity environment, and falling off of deposited toner is suppressed. In theimage forming apparatus comprising a photosensitive drum (100), a cleaning blade (601) for removing toner, a section (603) for containing toner removed by the cleaning blade (601), and a seal sheet (602) for preventing leakage of toner, in order to effect neutralization on the upstream side, in the moving direction of the drum (100), of the seal sheet (602), the difference in work function between the seal sheet (602) and the photosensitive drum (100) is set at 0.25 eV or above.

Description

technical field [0001] The present invention relates to a process cartridge and an image forming apparatus including a cleaning member for removing developer remaining on an electrophotographic photosensitive member after a developer image is transferred from the electrophotographic photosensitive member to a recording medium. Background technique [0002] An electrophotographic image forming apparatus forms a latent image on an electrophotographic photosensitive member, then develops the latent image into a visible image using a developer (hereinafter referred to as "toner"), and transfers the toner image to Print to the recording medium to complete the image formation. In such an electrophotographic image forming apparatus, a cleaning device removes foreign matter such as transfer residual toner from an electrophotographic photosensitive member after transfer is completed in preparation for reuse of the electrophotographic photosensitive member. [0003] Figure 9 The pho...
